伊朗核項目協議將於1月20日開始生效

A deal to limit Iran's nuclear program in exchange for limited sanctions relief is set take effect January 20.

Officials from both sides confirmed the start date Sunday, after experts spent weeks discussing how to implement the six-month pact they first agreed to in November.

Iran will limit its uranium enrichment to five percent and reduce its stock of higher-enriched uranium, while also allowing United Nations inspectors to access nuclear facilities.

In exchange, the United States and European Union will ease sanctions that have squeezed Iran's economy.

Iran and the six world powers, which include the U.S., Britain, China, France, Russia and Germany, will use the six months to continue negotiations on a long-lasting deal to address fears that Iran is seeking to build nuclear weapons.

U.S. Secretary of State John Kerry said reaching a comprehensive agreement will be tough, but that the negotiations are the best way to resolve the issue "peacefully and durably."有關伊朗限制其核項目以換取國際社會放鬆制裁的協議定於1月20日開始生效。

協議雙方的官員星期日確認了協議生效日期。在此前數星期裏，專家們討論瞭如何實施這項去年11月達成的有效期爲半年的協議。

伊朗將把鈾濃縮純度限制在5%，並削減高純度濃縮鈾的儲備量，同時允許聯合國檢查員進入其核設施。

作爲交換，美國和歐盟將放鬆對伊朗的制裁。伊朗經濟受到制裁措施的遏制。

伊朗和世界六強國將利用這半年時間繼續就一項長期協議進行談判，以打消對伊朗尋求研製核武器的憂慮。六強國包括美國、英國、中國、法國、俄羅斯和德國。

美國國務卿克里說，達成一項全面協議將是艱鉅的，但談判是“和平及持久”解決這一問題的最佳途徑。
